ASTRA provides advanced crystal structure analysis of almost any kind of crystalline materials except proteins. Traditional specialization are modulated structures. ASTRA currently runs three laboratories utilizing complementary diffraction methods: x-ray diffraction on single crystals, x-ray diffraction on powders and electron diffraction tomography on microcrystals. For solution of crystal structures, inhouse developed methods and programs are used: Superflip, Jana2006 and Dyngo. The throughput of ASTRA is about 500 samples per year.
